Application filed June 9, 1.913. Srial No. 772,729.

To all whom it may concern: Be it known that I,

States N av have invented certain new and useful Improvements in Electric Detaching Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in electric detaching apparatus, and relates more particularly to apparatus of this nature which is capable of supporting various objects and which may be actuated by an electric current so as to release the same.

Another and more specific object of the invention resides in the provision of an apparatus of this nature, which includes a supporting hook pivoted at one end and adapted to be held in operative position by engagement with a trigger rod, and a solenoid for withdrawing said rod from ongagement with the hook, whereby the object supported thereon will be released.

he invention also aims to generally improve electric detaching apparatus of this nature to render the same more efficient, re liable, and commercially desirable.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described, and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

. Figure 1 is a side elevation, partly broken away and partly in section, of my electric detaching apparatus, Fig. 2 is a fragmentary view thereof, showing the'hook detached from the trigger rod, Fig. 3 is a front elevation, Fig. 4 is a rear elevation, Fig. 5 is a detail perspective view of one end of the trigger rod, and, Fig. 6 is a longitudinal sectional view through the solenoid and easing- In the following description and accompanying drawings, similar parts will be referred to and designated by like reference characters.

Referring in detail to the drawings by numerals, 1O designates a suitable base, to

SoLoMoN ENDEIQ, a citizen of the United States, of the United the rear side of which a solenoid case 11 is secured. The case is cylindrical in crosssection, open at each end, and formed upon its inner end with an annular attaching flange 12, through which suitable fasteners 13 extend. A spool 14 forming a part of a solenoid is containedwithin said case and has its ends threadingly engaged therewith. An insulated wire 15 is wound around the spool in the usual manner and is extended through openings 16 formed in the case, as clearly shown in Fig. 1. The wire may be connected to any suitable means so that a current may be caused to flow therethrough at will. It will be noted that the ends of the spool close the ends of the case 11 so that the winding of the solenoid is fully pro tected.

A trigger rod 17 extends longitudinally through the spool and also extends through the base 10. The rod is formed in sections, as clearly shown in Fig. 6, which sections are secured to one another as indicated at 18. The section 17 is responsive to magnetic waves, whereas the other section is not, so that when the solenoid is energized, the trigger rod will be moved longitudinally. A knob 19 is threaded to the rear extremity of the trigger rod and when said rod is in its forward position, engages the end of the spool. The forward end of the trigger rod is enlarged to form a rectangular block 20, which is provided with a depending lip or flange 21. The base 10 is recessed, as indicated at 22, to form a pocket into which the block is adapted to be partly drawn. An expansive spiral spring 23 encircles the trigger rod and is housed within a pocket or recess 22. The spring by bearing against the rear wall of the recess and a washer 24 serves to hold the trigger rod normally in its forward position. A face plate 25 is secured within a shallow recess formed in the front face of the base 10 by means of suitable fasteners 26 and extends open end of the recess 22. The face plate is formed with an opening which conforms to the shape of the block 20 and through which said block is adapted to slide. The lip 21 by engaging the outer face of this plate, limits the inward movement of the trigger rod.

A bracket 27 is secured to the front face of the base 10 above the trigger rod 17, by means of suitable fasteners 28. The

bracket 27 comprises a base .plate ,29, having a block 30 formed upon its outer face,

said block being bifurcated adjacent its tance from the base 10 and slightly above The hook 32 is doubly.

the trigger rod 17 curved, extends downwardly from the pin 33, then rearwardly and upwardly, as

clearly shown in Fig. 1. In its operative position, the free end of the hook rests upon and is supported by the block20, so that any object which is connected to the hook by a suitable fastener, such as the ring 34, is supported. The bracket 27 is formed with the flanges 35, which project downwardly on opposite sides of the block 20 so that the book 32 is held against lateral movement when engaged with said block.

When thesolenoid is actuated the trigger rod 17 is drawn rearwardly until the lip 21 strikes the face plate 25. This movement is sufficient to move the block 20 from engagement with the supporting hook 32, whereupon said hook swings to the position shown in Fig. 2 and drops the object which it supported. Should the device refuse to operate electrically, the knob 19 may be grasped so as to move the trigger rod manually, and thus detach the same from the hook 32.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that I have designed an electric detaching apparatus, which is capable of supporting various objects, such as life preservers, etc., in such a manner that they may be easily released by throwing a switch.

It is to be understood that while I have shown and described the preferred embodiment of my invention, I do not wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will fall within the spirit and scope of the invention.

Having thus described my invention, what I claim is l. A detaching apparatus comprising a base, a solenoid secured to one side of said base, the base being formed with a transverse opening, a trigger rod extending through said solenoid and opening, a block secured to one end of said trigger rod, an

apertured plate fitting over said opening, a :lip formed upon the block for engagement with .said plate, whereby the movement of the trigger rod in one direction is limited, spring means for holding the trigger rod normally in extended position, and a pivoted supporting member adaptedto be released by a movement of the trigger rod when the solenoid is energized.

2. In any electric detaching apparatus the combination with a base having a transverse opening extending therethrough, of a solenoid secured to one side of the base in alinement with said opening, atrigger rod extending through the solenoid and theopening in the base, an apertured plate secured to the base and extending across one. end of said opening, a block secured to one end .of the trigger rod and sliding through said apertured plate, the block being formed with a lip for engagement with said plate, whereby the movement of the trigger rod in one direction is limited, spring means for holding the trigger" rod normally in extended position, and a pivoted supporting member adapted to be held in operative position by engagement with said block.

3. In an electric detaching apparatus, the combination with a base,'of a solenoid secured to one side thereof, a trigger rod ex: tending through said solenoid and base, said base being recessed around the trigger rod, a block formed upon the forward end of said rod and adapted to be withdrawn partly within said recess, spring means housed within the recessfor holding said rod normally in its extended position, and a supporting member pivoted at one end and adapted to be held in an operative position by engagement with said block.

In testimony whereof I afiix my signature in presence of two witnesses. V
